Scraper Accommodating Different Sizes of Blades

ABSTRACT

A scraper has a blade holder that tapers from a wider width to a narrower width. A blade with a scraping edge is mounted on the blade holder with the scraping edge near to the narrower width of the blade holder. The blade is interchangeably mounted and can be replaced with other blades. The blades can have different widths for their scraping edges. The tapered shape of the blade holder allows blades with different widths of scraping edges to be used in the scraper without the blade holder interfering with the use of the scraper. Embodiments of the scraper have handles which may have features such as a hand rest near the blade holder to provide additional pressure and a ring at the end of the handle to provide additional pull. At least one embodiment of the scraper has a bearing surface to fit on a guide on a sharpener.

FIELD OF THE INVENTION

This invention relates to scrapers and more particularly to scrapers andinterchangeable blades of different sizes.

BACKGROUND

Scrapers are utilized in removing paint, finish and fine layers of woodamong other things in areas that motorized tools are unable to operate.Typically, scraper blades are sharpened freehand with a file after beingattached to a blade holder or handle by some means. It takesconsiderable practice, skill, and attention to the task to sharpen ablade by freehand methods and obtain a straight and sharp edge. A bladebeing freehand sharpened with a file usually results in the centerhollowed, edges rounded or a combination of both, resulting in a gougedor uneven work surface when the defectively sharpened blade is used onthe work surface. In addition to quality issues, the typical method ofsharpening a blade, for example, a scraper blade, presents safetyissues. In the sharpening process, pressure is applied to the blade witha file while moving the file across the blade. Workers sometimes slipoff the blade edge with the file while moving the hand holding the filetowards the blade, which can result in injury, such as a cut to the handthat is holding the file.

Understanding the dynamics to sharpen the blade does not always resultin the ability to apply that knowledge. It takes time and experience.Many workers never achieve this skill, even after considerable effort.The several embodiments of the present apparatus and method eliminatethe need to acquire the skill and provide a willing, but untrained,individual the ability to sharpen a blade in a safe, effective, andexpeditious manner.

Whether from improper shaping when being sharpened, or from wear overtime through repeated use and sharpening, scraper blades becomeunusable, and must be replaced. Therefore many scrapers are designed toaccommodate changing in new blades. However, the scrapers and theinterchangeable blades are closely matched in widths. This requires thepurchase and use of several scrapers if different widths of blades areto be used. Additionally, this matching between blades and scrapers,means smaller blades require the use of smaller scrapers, which reducesthe comfort and effectiveness of using the scrapers. There is a need fora larger scraper that can use blades of different widths to provide moresubstantial manual gripping, as well as reduce the number of scrapersneeded to cover a range of tasks.

RELEVANT ART

U.S. Pat. No. 523,908 by Sly is for a “Machine for Sharpening Shears.”In Sly, an arm is attached one of the shear halves. The shear half isplaced on a sharpening stone while the other end of the arm is placed ina guide. The arm keeps the shear blade at the correct angle while it isbeing moved on the stone.

U.S. Pat. No. 1,359,271 by Plummer is for a “Universal Tool Sharpener”.In Plummer, an abrading block rests on a base. A cylindrical guide barfixed at each end spans above the abrading block. A carrier is fittedover the end of the guide rod to mount it on the guide rod. Tools can befixed in the carrier and arranged so that their point or blade contactsthe abrading block. Sliding the carrier along the guide rod moves thetools point or blade along the abrading block to sharpen the tool.

U.S. Pat. No. 1,675,981 by Lees is for a “Graver Sharpener and FacetCutting Machine.” In Lees, a wet stone rests on a panel with a blockrunning along an edge of the wet stone and support guide block supportone end of each of two arcuate guide rods. The other ends of the guiderods are on support posts. A straight guide bar has nuts with aperturesat each of its ends and spans the arcuate guide rods and can slide alongthe arcuate guide rods. A block for holding a graver is slid over theend of the straight guide bar to assemble it to the guide bar. The blockcan pivot about the straight guide, and it can slide along the straightguide. A graver held by the block can be put in contact with the wetstone and moved along it to sharpen it, while being maintained at adesired angle.

SUMMARY

One embodiment of the present invention is a bladed tool and sharpenercombination with the means to abrade the blade edge square to its faceat an angle resulting in the blade being sharpened. The sharpener has asharpening element and a guide such as a guide rod. The bladed tool hasa bearing surface on it matching the guide. By placing the bearingsurface of the bladed tool on the guide rod of the sharpener, the bladeof the bladed tool can be maintained in contact with the sharpeningelement in correct orientation while being moved back and forth. In oneembodiment the bladed tool is a scraper. Alternative embodiments includeadapters that can be substituted into the combination tool and used tosharpen other bladed tools such as chisels. These adapters do not needto be permanently mounted as part of the combination tool to be used.Among other things, this provides a means of sharpening a larger varietyof blades and bladed tools.

At least one embodiment of the scraper also tapers at the end thatsupports the scraper blade. This taper allows the use of blades ofdifferent widths while avoiding access problems. When the end of thescraper has a blocked or square end, using a narrower blade means thatthe width of the scraper extends outside the width of the blade, and thesquare corners of the scraper interferes with reaching tight places,corners, etc. This can defeat one of the purposes of using a smallerblade.

As discussed above, the article and method of the present inventionovercomes the disadvantages inherent in prior art methods and prior artdevices. In this respect, before explaining at least one embodiment ofthe invention in detail, it is to be understood that the invention isnot limited in its application to the details of construction and/or tothe arrangement of the support structure set forth in the followingdescription or illustrated in the drawings.

DETAILED DESCRIPTION OF EMBODIMENTS

FIGS. 1, 2, 3, and 4 illustrate a first embodiment of a scraper kit,which includes a scraper tool and a sharpener, while FIGS. 5 and 5Aillustrate a scraper apart from the sharpener.

The embodiment of the scraper tool shown in FIGS. 1-5A includes bladeholder 105, scraper blade 107, bushing 109, and clamp screw 108.Referring now to FIGS. 5 and 5A, it can be seen that bushing 109 isremovable and provides a slide bearing 114 at least partially open witha slot along its length and a blade mount surface 115. Slide bearing 114is sized to fit a guide rod 101 such as shown in FIGS. 1-4. To sharpenblade 107 while mounted in bladed holder 105, slide bearing 114 isplaced over guide rod 101, blade holder 105 is rotated to bring blade107 into contact with the sharpening surface 116 of sharpening element102, and blade holder 105 is slid back and forth on guide rod 101 whilemaintaining contact between blades 107 and sharpening surface 116.

The sliding of blade holder 105 back and forth on guide rod 101 produceswear on slide bearing 114 and over time bearing 114 may become wornbeyond effectiveness. Because of this, in the embodiment shown in FIGS.1-5A, bearing 114 is made as part of removable bushing 109 which alsoincorporates blade mount surface 115. As shown in FIG. 5A, both blademount surface 115 of bushing 109 and blade 107 have apertures, blademount surface aperture 117 and blade aperture 118, respectively. Bladeholder 105 has an aperture, or hole 119, which may be threaded. Clampscrew 108 passes through blade aperture 118 of blade 107 and bushingaperture 117 of bushing 109 and threads into hole 119 in blade holder105 to clamp blade 107 and bushing 109 to blade holder 105. The blade107 typically is made of metal, such as steel. The bushing 109 may bemade of metal, plastic or other desired material.

Although the embodiment of FIGS. 1-5A has bearing 114 as a part ofremovable bushing 109, that is not a requirement. Other embodiments mayhave bearing 114 made integral to the scraper, either from the samematerial as the rest of the scraper, or as an insert resistant to wear,such as a metal insert. Similarly, other embodiments may have a blademount surface integral to the scraper as opposed to being part ofremovable bushing 109. In the embodiments shown in FIGS. 1-5A, havingblade aperture 118 and bushing aperture 109 arranged concentrically overholes 119 when blade 107 and bushing 109 are mounted on blade holder105, allows a single clamp screw 108 to clamp both items onto bladeholder 105. An alternative mechanism could be used for clamping insteadof a screw, if desired. It is conceivable that, in other embodiments,blade 107 could be made permanent in blade holder 105, but that isunlikely, since blade 107 wears from use and sharpening, and once apermanent blade is worn, its whole scraper would have to be thrown away.Additionally, in some embodiments, slide bearing 125 may be recessed ina notch in blade holder 126 with surfaces of the notch leading back toterminate at the bearing surface. The walls of the notch facilitatekeeping the scraper engaged. Also, while the bearing surface is shown ascylindrical, it could also be comprised of tow or more flat surfaces.

Handle 120 extends from blade holder 105. Where handle 105 joins bladeholder 105 there is a broad, curved, indented design element, or handrest 106, in the top surface of the scraper to fit the heel of aperson's palm to aid in applying pressure to the blade and or worksurface. Hand rest 106 is most fully seen in FIG. 4 and may be seen inprofile in FIG. 3. There are several manners in which hand rest 106 maybe used. One manner includes pressing into hand rest 106 with the heelof the palm of one hand to apply pressure.

At the end of handle 120 distal from blade holder 105 is ring 121. Ring121 is large enough that at least one finger may be inserted through itto pull the scraper. This provides a strong, positive grip for pullingthe scraper while it is in use. The combination of hand rest 106 andring 121 on the scraper allows a user to both apply pressure to thescraper and pull steadily notwithstanding the pressure being applied. Asa grip, ring 121 allows the scraper to be used easily at a wide range ofangles.

In the embodiments shown in FIGS. 1, 2 and 6, the sharpening toolincludes a frame 100, a guide rod 101, a sharpening element 102. Guiderod 101 in this embodiment has a cylindrical shape and can be made ofsolid or hollow material of most any kind that would be rigid enough andstrong enough to resist deflection. Guide rod 101 is held between twoparallel uprights 122 extending from base 123 of frame 100, which couldbe made of most any material. The presence of two uprights in theembodiments shown allows guide rod 101 to be securely supported at eachend which provides a level of rigidity and limits the sliding motion ofa blade holder. However, other embodiments may have frames with otherconfigurations and two uprights are not a requirement. Frame 100 may bemade by casting, molding, or by other means. Sharpening element 102 inthis embodiment is a mill bastard file. Other embodiments may employother sharpening elements such as files of other grades, a diamondabrasion tool, a honing stone, etc.

In the embodiments shown in FIGS. 1-5A, the position of sharpeningelement 102 may be adjusted, and sharpening element 102 may even beremoved and replaced. Sharpening element 102 is clamped into placebetween base 123 and the bottom of uprights 122 by tensioning screw 104and nut 103. Nut 103 is positioned over slot 124 and tensioning screw104 is turned through nut 103 until its end contacts the bottom ofsharpening element 102 and generates enough force to securely holdsharpening element 102 in place. Slots 124 allow tensioning screws 104and nut 103 and each end of sharpening element 102 to be moved so thatthey are centered on sharpening element 102 as well as allowing theoverall position of sharpening element 102 to be adjusted. Sharpeningelement 102 may be removed by sufficiently relaxing the hold oftensioning screws 104.

FIGS. 6 and 7 show the same sharpening tool of FIG. 1 being used with analternative blade holder 110, for use in holding a different tool to besharpened, such as a chisel. In this case, a chisel toe plate 111 issecured to the blade holder 110 by means of clamping screws 112. The toeplate 111 has a recess for receiving the blade of the chisel, as shownin phantom in FIG. 6. There also is a set screw 113, which clamps thechisel blade against the toe plate 111. Blade holder 110 has a slidebearing 125 partially opened along its length which engages the guiderod 101 in the same manner as the previously described bearing 114.Other shapes of toe plates and/or tool holders could be used instead ofthe toe plate 111 and blade holder 110 for holding other tools.

Referring now to FIG. 7A, another embodiment of a blade holder 126 isshown. In that embodiment, bearing cap 127 allows partially open slidebearing 128 on blade holder 126 to be closed around a guide rod after ithas been positioned on the guide rod. Although the bearing cap 127 inFIG. 7A provides a 360 degree enclosure of the rod, other embodiments ofbearing cap 127 may create a wrapping of less than 360 degrees about theguide rod. The extent of wrapping about the guide rod deemed necessaryis determined by the application and the loads generated by theapplication.

FIG. 7B is an exploded perspective view of the blade holder 126 of FIG.7A. In FIG. 7B additional screws 129 and matching apertures 130 providethe means of attaching bearing cap 127 to blade holder 126. Otherelements of blade holder 126 shown in FIGS. 7A and 7B are similar to theembodiment of blade holder 110 shown in FIGS. 6 and 7.

FIG. 7C is a perspective view of an embodiment of blade holder 126 whichhas clip 131 attached near, or on, open bearing 128. Clip 131 has aspring quality to it. Once bearing 128 of blade holder 126 is installedon a guide such as guide rod 101 in the sharpener discussed above, clip131 retains bearing 128 in contact with the guide. Clip 131 may beattached with a screw or any of several possible alternative means ofattachment. It may also be located on either side of bearing 128.

FIGS. 8A, 8B, and 8C show several embodiments of slide bearing 125. Inthe embodiment shown in FIG. 8A, the internal surface of slide bearing125 encloses an angle greater than 180 degrees. In this embodiment slidebearing 125 can “snap” over guide rod 101 and thereafter provide somemeasure of retention of blade holder 105 without assistance. In order todo this, slide bearing 125 must have sufficient flexibility. Thisflexibility may be due to the inherent flexibility of the material ofbearing 125 or may result as much from the design of bearing 125. Theembodiment of slide bearing 125 in FIG. 8B does not have the capabilityto wrap around guide rod 101. Because of this, slide bearing 125 of FIG.8B may be made of a more rigid, or harder, material. This may bedesirable for wear durability. The embodiment of slide bearing 125 shownin FIG. 8C has a smooth bearing surface in contrast to the embodimentsof bearing 125 in FIGS. 8A and 8B, which have surface reducing grooves.

Turning now to FIG. 9, FIG. 9 shows an embodiment of scraper 210 with atapered blade holder 220. Blade holder 220 tapers from a wider widthwhere it joins the rest of the scraper to a narrower width where it endsand backs the edge 231 of blade 230. In this embodiment blade holder 220joins the rest of scraper 210 at hand rest 240 which is shaped toaccommodate a hand bearing down to increase contact pressure at edge 231of blade 230. Opposite to blade holder 220, handle 250 extends from handrest 240.

In FIG. 12, several different blades are shown. Each blade comprises aplate 232 and an edge web 234 running along one edge of plate 232. Plate232 has a top surface 235, a bottom surface 236, a back edge 233, twoside edges 237, and another edge from which edge web 234 extendsdownwardly from plate 232 along the edge opposite to back edge 233. Edgeweb 234 may be formed by bending down a section of a metal blank. Alongthe length of edge web 234 opposite to where it joins plate 232 runsblade edge, or edge, 231. This is the edge used for scraping. Topsurface 235 of blade 230 is the surface that contacts blade holder 220when blade 230 is mounted in scraper 210. In the embodiments shown inFIG. 12, blades 230 each have blade aperture 237 through plate 232.Blade aperture 237 is used to mount blade 230 to blade holder 220.

To the left in FIG. 12 is shown a smaller blade 230 such as is shownmounted in scraper 210 in FIG. 9. In the embodiment shown to the left,plate 232 is the same width as edge web 234 and edge 231 and side edges237 extend straight back to back edge 233. Returning to FIG. 9, it maybe seen that since blade 230 is only as wide as edge web 234 and edge231, blade 230 will only cover a portion of the bottom of blade holder220 as it extend back beneath it.

In the center of FIG. 12 is shown a middle size blade 230 such as isshown mounted in scraper 210 in FIG. 10. In the embodiment shown from abottom perspective in the center, back edge 233 of blade 230 is as wideas the wider part of blade holder 220, and side edges 237 run parallelout to the edge from which edge web 234 bends downwardly. Turning toFIG. 10, it may be seen that the shape of plate 232 in that embodimentcauses edge web 234 and edge 231 to be wider than the end of bladeholder 220 and that edge web 234 and edge 231 are about the same widthas the end of hand rest 240.

To the right in FIG. 12 is shown a larger blade 230 such as is shownmounted in scraper 210 in FIG. 11. In the embodiment shown to the right,back edge 233 of blade 230 is as wide as the wider part of blade holder220, but side edges 237 diverge outwardly to a wider edge from whichedge web 234 bends downwardly. Turning to FIG. 11, it may be seen thatthe shape of plate 232 in that embodiment causes edge web 234 and edge231 to be wider than the part of blade holder 220 that joins hand rest240 and that edge web 234 and edge 231 are the widest portions of theentire assembly. Additionally, in the embodiment of blade 230 shown tothe right in FIG. 12 and in FIG. 11, another feature may be seen inplate 232 of blade 230.

The tapered shape of blade holder 220 on scraper 210 allows scraper 210to accommodate several sizes of blades. For work on narrower areas, asmaller blade may be mounted on blade holder 220 without the corners offree end 221 of blade holder 220 interfering with reaching confinedareas. The use of a small blade in a full sized scraper provides thegripping advantages that come with a fill sized handle. Larger bladesizes may be used to cover larger areas. The ability to accommodateseveral widths of blades allows a single size scraper to perform severaltasks and does away with the need to purchase several scrapers toperform a range of tasks.

Operation

As illustrated in FIG. 1, the blade holder 105 and its attachments aremounted on the guide rod 101 and are positioned to be pulled along thesharpening element 102 to the position shown in FIG. 2 in order tosharpen the scraper blade 107. The sharpening element 102 in thisembodiment is a file and cuts only in one direction, so after completinga first pass from right to left (from the position shown in FIG. 1 tothe position shown in FIG. 2), the blade holder 105 is placed back inits original position shown in FIG. 1 and is pulled across the file 102again for further sharpening. Once the scraper blade 107 has beensharpened, the scraper tool is disengaged from the guide rod 101 asshown in FIG. 5, ready for use on a work surface. FIG. 3 shows how thebushing 109 is received in a recess in blade holder 105, and how blade107 is clamped against the flat portion of the bushing 109 and againstthe blade holder 105 by means of the clamp screw 108. It also shows howbearing 114 wraps around the guide bar 101, as discussed above withrespect to FIG. 8A. This bearing 114 has grooves in the curved surfacethat wraps around the guide bar 101 to reduce the surface area ofcontact between the bushing 109 and the guide bar 101.

As the scraper blade 107 is sharpened and mass is lost from the blade107, the angle between the tip (the sharp edge) of the blade 107 and thesharpening surface 116 of sharpening element 102 is reduced, whichresults in a smaller angle on the edge, but sharper scraper blade 107.

The arrangement shown in FIGS. 1, 2, 3 and 4 is for a right handedperson, with the scraper blade 107 positioned on the left side of theguide rod 101. Alternatively, for sharpening elements 102 that act inonly one direction, the sharpening element 102 can be turned 180 degreesand the sharpening motion would be accomplished with a push rather thanpull, or if the blade holder is being held by a left handed person, hecould turn the sharpener 180 degrees and push the blade holder 105 alongthe guide rod 101 to sharpen. This enables both left and right handedpeople to share sharpening tool without changing the set up. As thesharpening element 102 is worn with use, it can easily be repositionedso that fresh and or unworn areas of the sharpening element 102 contactthe blade 107 by loosening the tensioning screws 104 and the nut 103 andrepositioning the sharpening element 102.

The frame 100 holds the guide rod 101 parallel to the sharpening element102 and at a height conducive to enable sharpening of the scraper blade107.

FIG. 6 shows the frame 100 and assembly being utilized to sharpen achisel. In this arrangement, the chisel is moved across the sharpeningelement 102 parallel and square to sharpening surface 116.
